I play an upright piano with particularly heavy keys, and whenever I'm learning a very fast song (e.g. parts of Clementi Op.36 No.5) I wonder if even the composer couldn't have played it on my piano due to its key weight and recoil time.
From an analytical perspective, are there pianos considered "in good playing condition" for which the keys' action mathematically forbids a humanly playable speed (like certain runs and trills in the link)?
Or, from a musician's experience, are there instances where an expert pianist has been unable to perform on a concert piano due to aspects of the keys' action, or where a piano first required special regulation to make very fast playing possible?
Edit: I'm an amateur, so obviously my technique precludes a large range of humanly possible speeds. But as an example, there are many things I can do on an unweighted synth that I cannot replicate on my piano. I am wondering if expert pianists face this problem even from one piano to another.
